Architecture enforcement:
- Install a repository-owned rustc wrapper for ordinary cargo check,
build, and test commands. Resolve compiler item identities so renamed
imports and helper wrappers cannot hide spawning, timing, blocking,
polling, thread, or runtime-driving capabilities.
- Define the execution-owner crates and reject dependencies from those
substrates back into Myelin policy. Add compile-pass and compile-fail
contracts for actor helpers, execution owners, test waits, forbidden
capabilities, suppression attempts, and owner dependency inversions.
Execution ownership:
- Add engine-owned actor timers with cancellation and generation identity,
then migrate lifecycle deadlines and protocol ticks off application
tasks. Keep networking, process output, telemetry, and blocking provider
calls in their approved I/O substrates.
- Move process spawn, wait, signal, Unix listener, and output-following
mechanics into swactor-process. Isolate Vast.ai blocking HTTP mechanics
behind its adapter while actors retain retry, recovery, and provisioning
decisions.
Myelin control flow:
- Rework manual control, worker lifecycle, provisioning, provider recovery,
job deployment, distribution, edge orchestration, and shutdown as actor
state transitions and typed effects. Preserve durable provider adoption
and command outcomes across graceful and abrupt restarts.
- Replace controller loops and timer-forwarding tasks with actor messages;
leave substrate tasks as cancellable observation streams with no durable
policy state.
Properties and resource ownership:
- Add deterministic engine and component properties, a stateful mock-VastAI
lifecycle model, persisted regression cases, controlled fault injection,
and a bounded nightly workflow covering restart and teardown behavior.
- Terminate reply observers, cancel telemetry collectors, bound dashboard
projections, and release child observers, file descriptors, process
records, and inode-verified Unix sockets on every terminal path.
Verified with the compiler-policy contracts, 105 Myelin library tests, 32
swactor-process tests, telemetry cancellation contracts, randomized
stateful restart cases, cargo check, and formatting checks.
Add actor-backed manual node provisioning, control-plane endpoints, and fleet UI assets with durable provider lifecycle handling.
Simplify Myelin orchestration, node runtime, staging, and telemetry paths while removing obsolete engine-builder, dashboard-view, and local-mock implementations.
Align runtime delivery, data-plane, distribution, job-runner, process, telemetry, dashboard, Vast.ai integrations, and their tests with the revised actor and transport contracts.
The crate is the per-node metrics/logging pipe with a universal
subscriber endpoint, but "datastream" kept getting misread as a general
messaging plane. Rename crate, module paths, and public API
(`DatastreamEndpoint` → `TelemetryEndpoint`, etc.) so misuse is visible
on sight.
Renamed contracts (all in-repo producers/consumers migrated):
- env vars `MYELIN_DATASTREAM_*` → `MYELIN_TELEMETRY_*`
- artifact `datastream.ndjson` → `telemetry.ndjson`
- actor names `telemetry-publisher` / `telemetry-sink`
- wire ALPN `swactor/telemetry/0`
- `DATASTREAM_SPEC.md` → `TELEMETRY_SPEC.md`
Also fixes two latent test breaks: `process` and `iroh-driver` tests
imported `DatastreamEvent` from the crate root, which was never
re-exported; they now use the observer path `telemetry::frame::`.
Introduce the swactor engine: a swactor-owned composite that retains a
selected execution substrate, drives the core runtime, and hosts the
async/blocking/timer work that backs actors. Integrations receive one
cloneable EngineHandle and never construct or borrow a raw Tokio
runtime/handle.
Engine crate (crates/engine):
- The contract: spawn / spawn_blocking / timer / interval / now, a
per-implementation capability model with construction-time binding
(require()), and engine-owned time. The engine owns all progression;
actor handlers stay synchronous and never .await.
- TokioBackend owns the Tokio runtime and schedules core ticks and
supporting futures on it; SteppingBackend is a single-threaded
deterministic scheduler with virtual time (the non-Tokio portability
proof). Core is driven through its existing tick() surface; a
self-rescheduling CoreDriver is installed at construction and is the
sole place permitted to call try_tick.
iroh-driver:
- Receives an EngineHandle instead of a raw Tokio Handle. Accepts,
reads, dials, writes, endpoint construction, and teardown schedule
through it; required capabilities (tasks/timers/io) are validated
before the endpoint binds. Engine-hosted interval pumps drive
actor-bridge, datastream, and edge ingress.
myelin:
- One node/orchestrator engine owns core, protocol tick injection, and
transport progression; the application loop only drains
integration-owned queues. Stage-shard process readers, delayed actor
messages, helper stdout/stderr, prompt RPC, and CPU sampling all
schedule through the engine (spawn_blocking / engine tasks / timers).
- Removed the split-engine APIs: install_actor_bridge_pump(period) and
spawn_protocol_ticker(period) use each component's stored engine;
deleted the no-op pump_network callback and its plumbing; deleted the
dashboard raw-Tokio/standalone-runtime conveniences.
Enforcement:
- A clippy disallowed-methods boundary forbids direct runtime/scheduling/
time/core-driving bypasses, denied in swactor-engine, iroh-driver, and
myelin. Retained excluded uses (VastAI provider, provider process
supervision/log capture, OS-signal/stdin/process-control sequencing)
carry narrow allowances with reasons.
Verification:
- Engine contract + unit tests (incl. the SteppingBackend portability
proof), iroh integration tests (capability rejection before binding,
multi-node actor behavior), and a production execution-composition
smoke test that observes engine-driven actor progress with no ambient
Tokio runtime and no manual tick/pump. Workspace all-target/all-feature
clippy and tests are green.
Specs co-located with their crates: ENGINE_SPEC.md in crates/engine,
IROH_DRIVER_SPEC.md in crates/iroh-driver. VastAI remains explicitly out
of scope pending its separate redesign.
Trim the datastream crate to its dumb-pipe core: drop the frame-timing sidecar, make mux positions gap-free for accepted frames, and simplify the endpoint fanout.
- mux: defer position assignment from submit to drain so an overflowed submission no longer consumes a position (no synthetic gaps); submit now returns bool and the Mutex<Receiver> is removed since positions are assigned only to accepted frames
- endpoint/mux: switch from std::sync::mpsc to crossbeam-channel and drop per-event event_matches_request filtering — request filters now apply only to the initial catalog snapshot, and future events broadcast to all subscribers
- endpoint (DeliveryFanout): snapshot sender handles under the lock and deliver outside it via FanoutTarget/FanoutReport, so large batches or slow subscribers no longer block subscribe/snapshot control-plane ops
- emit/endpoint/producer: drop set_frame_timing_enabled/frame_timing_enabled and the Position return from submit_record/submit_text/submit_bytes, and add submit_text_owned taking owned String
- timing/lib/spec: delete the timing module and FRAME_TIME_CHANNEL/FRAME_TIME_CHANNEL_ID/FrameTimeSample re-exports (including the auto-registered timing channel in ChannelCatalogState) and renumber the DATASTREAM_SPEC.md section references across frame/ingest/store/mux
- tests: remove the 567-line shared datastream_support/mod.rs harness

Promote pipeline-parallel-inference to a first-class app and consolidate observability on the datastream wire, decoupling the dashboard crate from `distribution`.
- apps/pipeline-parallel-inference: move the example out of `examples/` into `apps/` as its own workspace, rename binaries to `pp-worker`/`pp-orchestrator`, and strip release binaries
- cluster: add `ClusterNode`, a synchronous facade over the actorized distribution protocol (IrohDriver + per-node Runtime hosting Swim/Registry/Metadata/Directory actors with a `MembershipFanout`), replacing ad-hoc `driver.node()`/`tick()` call sites
- fleet: add per-node fleet telemetry that ships identity/resource records as `DatastreamFrame`s over the cluster transport to the orchestrator's `DatastreamSink`, folded into a `FleetView` on a 3s tick
- provision: add best-effort, opt-in SSH boot-phase telemetry (`PP_DEPLOY_KEY`) that streams rented-node boot logs onto the orchestrator's datastream as `proc.boot.<stage>.*`
- dashboard: rewire the crate dependency from `distribution` to `datastream`, drop the standalone `swactor-datastream-dashboard` binary, and rewrite `datastream_source.rs` to demux per-node frames into Overview/Distribution/Fleet views with live-node TTL filtering
- distribution: refresh dist/netmap plugin copy and README from "Kademlia routing" to gossip-directory terminology
